Fix 1: Verify Power Supply (Works 38% of Time)

Why This First: No power = dead dock. Seems obvious, but connections loosen, outlets fail, adapters die.

Symptoms:

• No LED light on dock at all
• Dock was working, suddenly dead
• Recently cleaned around dock
• Roborock sits on dock but nothing happens

How to Fix:

Step 1 - Check Power Adapter Connection:

At the Dock:

1. Locate power cord entering back of dock
2. Barrel connector (cylindrical plug)
3. Push firmly - should be fully inserted
4. Wiggle test:
   • Connector shouldn't move
   • If loose, not making good contact
5. Try unplugging and replugging
   • Ensure complete insertion

At the Wall:

1. Check power adapter plugged into outlet
2. Push adapter firmly into outlet
3. Wall wart style adapters can work loose
4. Check adapter LED (if present)
   • Some Roborock adapters have small green LED
   • LED on = adapter receiving power

Step 2 - Test Outlet:

1. Plug another device into same outlet
   • Phone charger, lamp, etc.
2. Device works?
   • Outlet good → check adapter/dock
3. Device doesn't work?
   • Outlet problem:
     • Check circuit breaker
     • Try outlet reset button (GFCI outlets)
     • Test different outlet

Step 3 - Inspect Power Cord:

1. Follow cord from adapter to dock
2. Check for damage:
   • Cuts or fraying
   • Kinks or pinches
   • Pet chew marks
   • Melted sections
3. Gently flex cord while observing dock LED
   • If LED flickers = damaged wire inside
   • Intermittent connection

Step 4 - Check Power Adapter:

Roborock Charging Dock Specs:

• Output: 20V DC, 1.2A (24W)
• Listed on adapter label

Adapter Health Check:

1. Feel adapter temperature (after 5 minutes plugged in)
   • Warm = normal
   • Hot/burning = failing adapter
2. Check for buzzing/humming
   • Slight hum = normal
   • Loud buzz = failing
3. Look for burn marks on adapter casing
4. Test with different outlet (rules out outlet issue)

Time: 5-10 minutes
Cost: Free (unless adapter replacement $15-25)
Success Rate: 38%
Difficulty: Easy

💡 Pro Tip: Keep dock on dedicated outlet (not shared with high-draw appliances). Shared circuits can cause voltage drops affecting dock operation.

Fix 3: Verify Dock Placement and Alignment (Works 12% of Time)

Why This Matters: Unstable or misaligned dock prevents proper pin contact.

Symptoms:

• Roborock struggles to dock
• Sometimes charges, sometimes doesn't
• Roborock sits at angle on dock
• Recently moved dock or cleaned floor
• Charging pins look clean

How to Fix:

Step 1 - Check Dock Surface:

Ideal Dock Placement:

1. Hard, level surface (tile, hardwood, vinyl)
   • NOT thick carpet
   • NOT rugs (dock tilts)
   • NOT uneven floor
2. Against wall for stability
3. Clearance requirements:
   • 0.5m (1.5 ft) on each side
   • 1.5m (5 ft) in front
   • No obstacles blocking approach

Problem Surfaces:

• Thick carpet: Dock sinks, pins misalign
• Uneven tile: Dock rocks, inconsistent contact
• Area rugs: Dock slides, Roborock misses pins

Step 2 - Test Dock Stability:

1. Press down on dock gently
2. Should not rock or tilt
3. If unstable:
   • Move to level surface
   • Or place thin hardboard under dock
4. Check against wall
   • Dock should sit firmly against wall
   • Prevents backward movement during docking

Step 3 - Verify Pin Alignment:

1. Manually place Roborock on dock
2. Look at pin contact:
   • All 3 pins should touch Roborock contacts
   • Robot should sit level (not tilted)
   • No gaps between robot and dock
3. If misaligned:
   • Pins may be bent (see Fix 4)
   • Dock on uneven surface
   • Roborock wheel height issue

Step 4 - Check Infrared Sensors:

1. Dock has 2 infrared emitters (help Roborock find dock)
2. Look for 2 small dark "eyes" on dock face
3. Wipe clean with dry cloth
4. Should not be blocked by furniture or objects
5. Roborock uses these to home in on dock

Common Questions

Why did my Roborock dock suddenly stop working?

Most common causes: (1) Power adapter disconnected/failed (38%), (2) Dirty charging pins blocking electrical contact (24%), (3) Circuit breaker tripped (12%), (4) Damaged power cord (8%). Check power supply first - simplest fix.

Can I use a different charger for my Roborock dock?

No. Roborock dock requires specific 20V 1.2A adapter. Using wrong voltage damages dock or robot. Even "close" voltage (18V, 19V) can cause issues. Only use OEM Roborock adapter or exact replacement (20V 1.2A output).

My Roborock dock LED is on but robot won't charge - why?

Dock has power but charging pins not making contact. Most common: (1) Dirty pins/contacts (clean with alcohol), (2) Bent charging pins (straighten carefully), (3) Unstable dock (robot can't align properly), (4) Damaged robot charging contacts.

How long do Roborock charging docks last?

Roborock docks typically last 4-6 years with normal use. Failures usually: power adapter (2-3 years), charging pin springs (3-4 years), or circuit board (5+ years). Most dock "failures" are actually dirty contacts or loose connections, not actual dock death.

Can I repair Roborock dock myself?

Basic fixes yes: clean contacts, straighten pins, test power supply. Advanced repairs (circuit board, replace pins) require soldering and electronics knowledge. For major damage, replacement dock ($50-80) cheaper than pro repair ($80-120) and faster.

My Roborock charges for 5 minutes then stops - is it the dock?

Usually not dock. More likely: (1) Roborock battery calibration issue, (2) Overheating protection triggered, (3) Dirty charging contacts causing intermittent connection, (4) Battery failing (if robot old). Try battery reset procedure first.
